While Dancing With the Stars' Hayley Erbert and Derek Hough are happily preparing for the arrival of their first baby, the pair are also marking Pregnancy and Infant Loss Awareness Month by opening up about Ebert's first pregnancy, which ended in a miscarriage. "There are some things in life that change you forever," they wrote in a joint post via Instagram on Wednesday, October 15. "For us, this is one of those things. A chapter of love, loss, heartbreak, and everything in between. As we are now in October, Pregnancy and Infant Loss Awareness Month, we share this part of our story to honor our baby that never made it earthside. One in four pregnancies end in miscarriage, a silent heartbreak so many families know, and one we unfortunately had to experience. As we share this, know that there's a rainbow not far behind. ♥️🌈" The accompanying reel showed Erbert, 31, and Hough, 40, during Erbert's first pregnancy. "This video is a tribute to a part of our story," reads text that appears over the video. "A chapter of loss, love, celebration, heartbreak, and everything in between. Although we are so excited to be welcoming our rainbow baby so soon, we honor our baby that never made it earthside." Derek Hough's Wife Hayley Erbert's Baby Bump Album Highlights from the reel include the moment Erbert told Hough that she was pregnant and when they dressed their dogs in matching bandanas that read "big brother" and "big sister." The reel also showed footage from one of Erbert's sonograms and the pair revealing the pregnancy to their loved ones. In the final clip, they appear to be crying as they hold each other. Their Dancing With the Stars family showed their support in the comments. "My dear friend, you are the strongest person I know!" Britt Stewart wrote. "You simply radiate strength and light. Sharing your story will give so many people hope. I love you dearly ❤️❤️" Derek Hough Tears Up Recalling Wife Hayley Erbert's Brain Surgery on 'DWTS' "Love you both. ✨🕊️," added Jenna Johnson.
